(2014). Use of organomolybdenum compounds for promoted hydrolysis of phosphoester bonds in aqueous media. European Journal of Inorganic Chemistry, 2014(23), 3681-3689. doi: 10.1002/ejic.201402071http://hdl.handle.net/10400.26/22039The dissolution of the indenyl (Ind) complex [{(η5‐Ind)Mo(CO)2(μ‐Cl)}2] (1) in N,N′‐dimethylformamide (DMF) gives the ring‐slipped complex [(η3‐Ind)Mo(CO)2Cl(DMF)2] (2). The aerial oxidation of 2 leads to the formation of the dinuclear oxomolybdenum(V) chloride [Mo2O2(DMF)4(μ‐O)2Cl2] (3). The structures of 2 and 3·DMF have been determined by single‐crystal X‐ray diffraction. Compounds 1 and 3 were examined as promoters of phosphoester bond hydrolysis in para‐nitrophenylphosphate (pNPP), which was used as a model substrate. The reactions were performed in aqueous solution at 55 °C and followed by 1H NMR spectroscopy. For assays performed with 30–100 mol‐% of 1 or 3 relative to pNPP, both compounds promote the production of para‐nitrophenol (pNPh) from pNPP. Compound 3 is especially active in promoting the hydrolytic cleavage of the phosphoester bond (t1/2 < 80 min).engjournal article10.1002/ejic.201402071
